Needle-type composite insulators are molded in one piece from composite insulating material, with fixed metal pins at the base for direct mounting on crossarms, suitable for conductor support insulation in medium and low voltage distribution lines. The silicone rubber shed features a flexible material that resists impact and cracking better than rigid porcelain or glass products, and is less prone to damage from falling rocks or debris outdoors. The material is hydrophobic and dirt-resistant, maintaining stable insulation performance in foggy, dusty, or coastal salt-spray areas, extending inspection intervals. The product is lightweight overall, allowing single-person high-altitude installation and removal, improving grid maintenance efficiency. Widely used in rural distribution networks, industrial park internal supply lines, and short-distance mountain distribution branches, it serves as a premium replacement for traditional porcelain or glass needle-type insulators, fitting current urban and rural grid upgrade projects.
